This intermediate-level, 108-video training course teaches the ethical hacking tools and techniques needed to improve network security posture. CBT Nuggets trainer Keith Barker walks learners through building their own practice labs, including using evaluation software, and encourages them to not only watch the videos, but to practice everything hands-on in their own lab environment.

"By being aware of the security weaknesses that exist, and how hackers go about compromising systems due to those weaknesses, the administrator or engineer can do a better job of proactively finding the vulnerabilities and implementing countermeasures to reduce risk," Barker said. "Security is a never-ending process, and it pays to stay on top of it by being proactive and continuing to learn."
